hi,
Now that we have Python in IDL, I'm wondering if it's feasible to use something like PyQT widgets?
I recently tested my IDL application on a Mac, and I was disappointed with the circa-20-year-old Motif-based widget system that IDL for Mac uses. It was awful.
So, if it makes sense to use a Python-based widget system from within IDL code, could someone perhaps post an example of how to do this? Perhaps a simple top-level-base widget with a draw window?
thanks
Mark

thanks Chris! I will have a look at this - maybe I can figure out how to handle the events.
Is IDL 8.5.1 released?

It looks like IDL 8.5.1 just went live today!

A couple blog posts covering some of this are now available on the IDL Data Point web site:
http://www.exelisvis.com/Company/PressRoom/Blogs/IDLDataPoin t.aspx
Look for posts from October 2015 and January 2016.

That may be a topic for one or more future blogs by one or more of us here at Harris Geospatial Solutions. (Yes, that's the new official name for RSI/ITT VIS/Exelis VIS.)
We're always looking for IDL-oriented ideas.
